This piece of Java code shows how to convert an array to one of the Collection types, namely a List.
There is a class called Arrays (not to be confused with an array) that has a method called as List() which takes an array as argument and converts it to a List object. Generics can be used to specify the List elements type.
package org.best.example;
public class Main {
public void arrayToList() {
String[] cars = {"Dodge", "Chevrolet", "BMW", "Toyota"};
List<String> carList = Arrays.asList(cars);
for (String car : carList) {
System.out.println(car);
}
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new Main().arrayToList();
}
}
